If I’m married and divorced in another state after 23 years of marriage, how do I enforce continued payment of alimony?

If you are living in Florida and were awarded alimony from another state you can either file a Motion to Enforce in the original state, or domesticate the out of state Judgment in Florida and have the Florida Judge enforce the Judgment. You probably need an attorney.

Enforcement would typically be with the original court who entered the divorce. It would probably be by a motion to enforce or a motion for contempt. Consult a family attorney where the divorce was entered.
